'''Telepresence''' is the appearance or sensation of a person being present at a place other than their true location, via [[telerobotics]] or video.

Telepresence requires that the users' senses interact with specific [[Stimulus (physiology)|stimuli]] in order to provide the feeling of being in that other location. Additionally, users may be given the ability to affect the remote location. In this case, the user's position, movements, actions, voice, etc. may be sensed to [[Data transmission|transmit]] and duplicate in the remote location to bring about this effect. Therefore [[information]] may be traveling in both directions between the user and the remote location.

A popular application is found in [[videotelephony|telepresence videoconferencing]], the highest possible level of [[videotelephony]]. Telepresence via [[video]] deploys greater technical sophistication and improved fidelity of both sight and [[Sound recording and reproduction|sound]] than in [[videoconferencing|traditional videoconferencing]]. Technical advancements in [[mobile collaboration]] have also extended the capabilities of videoconferencing beyond the [[boardroom]] for use with [[Mobile device|hand-held mobile devices]], enabling collaboration independent of location.

A similar or identical concept is ''telexistence'', which was first proposed by [[Susumu Tachi]] in Japan in 1980<ref>S.Tachi, K.Tanie and K.Komoriya: Evaluation device of mobility aids for the blind,
 Japanese Patent 1462696 filed on December 26, 1980.</ref> and 1981<ref>S.Tachi, K.Tanie and K.Komoriya: Operation method of manipulators with sensoryinformation display functions, Japanese Patent 1458263 filed on January 14, 1981.</ref> as patents and the first report was published in Japanese in 1982<ref>S.Tachi and M.Abe: Study on Telexistence (I) -Desigan of Visual Display-, Proceedings of the 21st SICE Annual Conference, pp.167-168, Tokyo, July 28–30, 1982.</ref> and in English in 1984.<ref>S.
